The Kyrgyz Ala-Too (Kyrgyz: Кыргыз Ала-Тоосу, also Kyrgyz Alatau, Kyrgyz Range) is a large range in the North Tien-Shan. It stretches for a total length of 454 km from the west-end of Issyk-Kul to the town Taraz in Kazakhstan. It runs in the east-west direction, separating Chuy Valley from Kochkor Valley, Suusamyr Valley, and Talas Valley. Talas Ala-Too Range adjoins the Kyrgyz Ala-Too in vicinity of Töö Ashuu Pass. The western part of Kyrgyz Ala-Too serves as a natural border between Kyrgyzstan and Kazakhstan.
